CATALYTIC SYSTEM FOR POLYMERIZATION OF ETHYLENE, METHOD OF PREPARATION THEREOF, AND ETHYLENE POLYMERIZATION PROCESS

摘要

FIELD: polymerization processes. SUBSTANCE: invention, in particular, relates to catalytic system for homopolymerization of ethylene and copolymerization of ethylene with one or more alpha-olefins and conjugated dienes. System consists of catalyst A, catalyst B, and transfer agent, wherein catalyst A includes one or more organomagnesium compounds, transition metal compounds, and organic chloride that does not react spontaneously with organomagnesium compounds. When preparing system, organomagnesium compound is mixed with organic chloride and resulting mixture is added to transfer agent. When carrying out polymerization of ethylene, catalytic system is used in gas phase, suspension, solution, and for bulk polymerization. In addition to catalytic system, above-mentioned organic chlorides can be added into reactor. EFFECT: facilitated catalyst preparation control, increased catalytic activity at higher temperatures, and increased yield of polymer. 24 cl, 5 tbl
